Improvement in plows



. UNITED lSTATES PATENT OFFICE...

BENAIAH C. HOYT, OF PORT WASHINGTON, WISCONSIN.

IMPRovEMl-:NTIN PLows.-

Specification forming part of Letters Patent No- 15,654, dated September2, 1856.

To all whom 'it may concern:

Be it known that I, BENAIAH U. HoYr, ot'

Port Washington, in the county of Ozaukee,

and in the State of Wisconsin, have invented a new and usefulImprovement on the Rotary Cultivator-Plow and I do hereby declare thatthe following is a full and exact description thereof', as Vshown in theaccompanying draw l ings.' (See Figures l, 2, 3, 4t.)

The nature of my invention consists, first, in 4the construction ofaplow so as to enable the plowman to turn one or two furrows with'it atthe same time; second, the construction ot' a plow so that it may bearranged into a rotary' cultivator without diiculty; and, thirdly, toenable the plowman to increase or diminish the width ot' his work atpleasure.

To enable others skilled in the art to make and use my invention, I willdescribe its con'- struction and operation.

I commence with thefr'ame It. I make a straight standard,'A, the frontedge of which has a Vform. Near the bottom ot' this standard is 'asquare bearing, B, which enters` a corresponding hole in the points,Figs. 2 and 3. These points are made fast to the standard by screw andnut, at T, and side bolts, gg. Above the V"t'orm, and about two-thirdsthe length of the standard Afrom the bottom up, isa projecting piece ofiron, C, with a hole through it,

which receives a bearing or hook on thelowerl side and back end ofthebeam D. At the top end of' the standard is a round bearing, U, whichreceives a plate of iron that is made fast tothe top ofthe beam,togetherwith the cap H.

At a point opposite the projecting piece G,

I start two branches, t2 t3, from the standard A, which I carry up in acurve-line about halt'- way from thestandard A to the slot F, where Ibring the upper branch, t3, down and conneet ilrto the lower branch, t2,forming a slot,

r Y, for the bolt Z to work through. From thence I carry the singlebranch t2 still on and down about half-way from the slotY to the slot Fin the back part of thc frame It, where another branch, V, starts upvand back, forming a place forthe location ofthe handles. At the bottomof branch Vth'e frame R starts out in a sharp curve, through which isslot F. From thence I extend the same around in acurve and connect it tothe standard A at G. The beam D is constructed of wood, with a strap ot'iron on the top and bottom. The strap on the bottom terminatesin a hook,.which enters the projecting piece C on the standard A. The strap ot'iron on the top of beam D terminates in a wide/plate, a a. It has threeholes through it, two of which are to receive screw- 4bolts b b, and thethird, which is-between the two, is larger, and is made to Work on thebearing U under the cap H. Thus the beam is hinged to the standard, asdescribed, and put into a position corresponding with the handles andpoint and made fast by the use of bolts b b, passing through the c ap Hin to the .plate a a on the beam. The cap H is bolted to the topbra-moby?, of the frame R. The cap H and the beam D are made secure tothe top end gf the standard lA by the use of screw and nut I constructmy mold-boards in the followingl manner: Each cnltivator-plow has twomoldboards, made nearly ali ke. Th e'y revolve upon a central pivot oraxle. The frames thatcontain the mold-boards are made of cast-iron.

Around the hub, or near the center of those trames, start out eight datpieces ot' iron, something like the spokes of a wagon-wheel, leaving anopen vspace between them, as seen at I. The ends ot these short spokesare connected to a band, J. From this band radiate prongs X5, the endsol which `work in the'earth, .taking a iirm hold on the same, andsecures their motion. y These'ames described are concavo-` convex inform. The mold-boards -K K are constructed of thin wrought iron orsteel, corresponding in shape to the mold-board trames, into whichframes they are placed, andmade fast to `them by bolts ,P P, passingthrough them into the prongs X5. Y The axles E, upon which themold-boards revolve, are inclined forward to that degree 4that whenthemold-board frames 'are hung upon them the convexsides come neartogether, and are made to work together by means-ot' studs on the backsides of the righ t-hand moldboard fra-me, passing through the openspaces in the left-hand mold-board frame, as seen at L. At the centerot' the axle is an arm, extending back, passing throughl slot F, and ismade' secure to the frame R by screw and nut c4. `At l the end of theaxle E, I make fast the lower end of braces R7 N, extending them up toslot Y, where I make the top ends fast by the nseof bolt Z. To increaseor diminish the width' the axle that passes through slot F in frame R.

The operation of this plow is as follows: To turnbut one furrow, putonto the standard A point M. Make it fast to the standard, as abovedescribed. Swingthe beam to the right and the handles to the left untilthe left handle and beam is on a line with the landside of the point M.To turn two furrows at the same time, put yonto the standard point, Fig.3. Make the beam and handles fast on a line between the two mold-boards.

To make a cultivator of the plow, put onto the standard point, Fig. 2.Remove the moldboards K K by withdrawing the bolt Z at the top end ofbraces Rf' N, and also withdraw the short bolts P P, that pass throughthe moldboards K K into the'prongs X.

Having described the construction and operation of myrotarycultivator-plow, what I claim as rnv-invention, and desire to secure byLetters Patent, is

The adjustable rotary mold boards K K, combined with beam D and frame R,the whole being arranged in the manner and for the purpose set forth.
